Gunsmithing Best epoxy for polymer composite chassis repair

[Scottso]

Have a chassis, polymer composite over aluminum frame. Got it bead blasted for paint and needs bodywork, lol, the old paint hid a lot of imperfections. Anywho was thinking acraglas, but was told finished a little rough, was wondering if a similar type epoxy would be better and finish smoother than the acraglas. Thanks in advance

Yeah, just need to fill some divots and even out some areas, not put back together lol

They do make different levels of JB. Use a razor blade to apply it.
And why would you want to use something that’s weak?

jb is a two part epoxy, strong like devcon and marine tex. if you are filling holes, and sanding, its great.

why not bondo?

West Systems epoxy, 105 with either 205, 206 or 209 hardner depending on your climate, microballoons, finish with pin hole filler, wet sand and paint away

I would suggest epoxy putty. It's way easier to fill and work with and sand ect... you can control it so much easier and it will work well for what you want

X2 on West Systems.
It is by far the best stuff I've ever used.....and I've built surfboards, and boats, and RC cars, boats, planes......let alone the gun stuff.

They have the mostest bitchenest pumps that go into the containers......that are metered, exactly how everyone should do it.
1 pump resin, 1 pump hardener = perfect ratio
10 pumps resin, 10 pumps hardener = still the perfect ratio

I would do 105 resin and 207 hardener myself.

Thanks, I’ll look into the West stuff, bondo was suggested basically for “body work” once paint was removed showed all imperfections
